SPRINGWORK.

Specficaton of Letters Patent.

Patented Sept. 5, 1905.

Be it known that I, JoHN A. S'rArLns,a citizen of the United States,residing at Newburgh, in the county of Orange and State of New York,have invented certain new and useful lmprovements in Springwork, ofwhich the following is a specilication.

In springwork as heretofore Constructed the Spring-supports, generallyin the form of IO hanging or drop wires, have been provided withcorrugations or bends usually in a vertical plane and the adjustabilityof the springs along these supports or the points at which the springswere set limited to the points at I5 which the bends or deflectionsoccurred. For example, when the deflections or bends were in the form ofeyes or of loops the points of attaching the springs were limited tothese loops` and when corrugations were employed the points ofattachment were limited to the top and bottom points thereof.

The object of my present invention is to improve upon this prior form ofconstruction and to provide an organization wherein the range ofadjustment of the springs along the length of the supporting-wires isincreased to include all points upon their horizontal portions, whetherwithin the frame with which they are associated or upon the end portionsresting on the frame. 1 accomplish this ob- Iiect by providing anorganization comprising supporting-wires without bends or corrugationsin their horizontal portions and intersecting or crossing' wires or keyshaving bends or detlections to receive the straight supportingwires andcoil-springs uniting with the wires at their crossing by a rotarymovement.

My invention is illustrated in the accompanying figuros of drawings,which show va- 40 rious forms of its embodiment, and in whiclr Figure 1is a cross-section of a frame, showing a straight or plainsupporting-wire and intersecting wires with springs supported at thepoints of intersection. Fig. 2 is a detail perspective view showing thespring and wires at the crossing-point, the intersecting wire having` aform of bend or corrugation that may be employed. Fig. 3 is a detailperspective view similar to Fig. 2, but showing a different form of bendor corrugation in the intersecting wire. Fig. Li is a side view showinga spring in elevation and the straight supporting-wire in section and anintersecting wire provided with a different form of bend l ordeflection. Fig. is a view similar to that shown in Fig. -i, the viewbeing taken upon the opposite side; and Fig. o' is a perspective viewshowing a spring and the intersecting or crossing wire arranged on topof the straight supporting-wire.

The support-ing-wires A are of suitable length to pass from one side tothe other of the frame of the chair-seat, bed-bottom, or Other articleof furniture, and each has an interior horizontal portion u, which isapproximately as long as the measurement of the Opening of the frame A',and preferably the ends are bent upwardly to provide a drop and are thenprovided with horizontal end portions u' and linished with means forattachment to the frame, preferably by providing points.which may bedriven into the frame, as shown in Fig. l. though, of course, it isunstood that the ends may be linished off in the form of eyes forreceiving nails or screws to secure the supports in place. The supportsare thus in the form of hanging or drop wires, and their main or bodyportions which are normally within the Opening of the frame when theparts are assembled, constitute the 30 means for supporting the usualinterior springs. The supports A may be of any form or conliguration andmay be attached to the frame at any place and in any manner, though theconstruction which l have here disclosed is best adapted for practicalwork.

The intcrsecting wires or keys B are provided with suitable bends ordefleetions arranged at their points of crossing with the support-s A,and these corrugations or bends may be made in any suitable manner andin any suitable form which will provide a depth such that when one ofthe interseeting wires is associated with a supporting-wire thenecessary space will be provided between the wires :for the small end ofthe spring to be interlaced by rotating the same, the wire of the Springpassing into the space between the respective horizoutal planes of thecrossing wires, under one and over the other, when the Spring has beengiven a full rotation and wedging against the wires to lirmly bind theparts together.

The bends or corrugations in the cross wires or keys B may be made inanysuitable form, the only essential feature being that they shall be ofsuch depth as to permit one or more of the coils of the springs to beintroduced between the supporting-Wire and the cross-key. As shown inFig. 2, the bend or loop is of substantially uniform curvature, while inthe form shown in Fig. 3 it is substantially angular in outline, and inFigs. 5 and 6 it is substantially U-shaped or has its ends nearertogether to more nearly resemble a closed loop or eye. The various formshere shown illustrate embodiments of this feature of the invention,which of course may be greatly varied in form and Configuration. In allinstances, however, the loop or bend is of such depth as to position thebody portion b' of the crossing or intersecting wire in a differenthorizontal plane from the supporting- Wire and to leave suficient spacebetween the bodies of the two wires to receive one or more of the coilsof the springs.

In the organizations above described the intersecting or crossing wiresare placed below the supporting-wires. It is obvious that thisarrangement may be reversed and that the intersecting wire may be placedabove the supporting-wire, the bends or loops of the intersecting wiresthen resting upon the straight supporting-wires, as shown in Fig. 6, andproviding the space for the introduction of one or more of the coils ofthe Spring, as before.

It will be observed that when the wires are assembled, Whether theintersecting wires be above or below the supporting-wires, the de pth ofthe bends ordeflectionsb provide the necessary space to receive one ormore of the coils at the small ends of the springs C, which areinterlaoed or interwoven by rotating the springs, the spiral formationof the strandsor coils bringing pressure upon the wires to bind themtogether and to bind the springs thereto, as is well understood in theart. In order to moreV effectually provide against displacernent alongthe supports, the latter may be roughened or barbed, as shown at ff inFig. 6, as an auxiliary means, if desired.

The leading ends c of the springs O are slightly larger than thefollowing two or three coils, as o' and 02,0r are somewhat tangential tothese coils, which are preferably of substantially the same size ordiameter, (and slightly smaller than the Width of the bends orcorrugations.) By this construction the leading ends more easily engagethe wires and the springs are more readily threaded in place. VVhen thesprings are rotated, the lower coil or coils (the number varyingaccording to the depth of the bends) will ride up the sides or faces ofthe bends and bring increased pressure thereon, which will slightlySpring the straight supporting-wire to tightly Wedge into the apeX ofthe Offset or bend. For example, in Figs. 2, 3, and 6 the interwovenportions of the springs rest upon and bind against the straight wiresand the opposite portions of the bends of the intersecting wires. InFigs. 4 and 5 thisaction is the same, and the interwoven coils tend toSpring the opposite Sides of the loop together, whereby a very stringentbinding action on the supportingwires is obtained. The tempered metal ofthe coils will bend the loops of the soft metal of the supports to avery perceptible degree.

It will be understood that the words straight and plain are employedherein in connection with the supporting-Wires to refer to and mean thattheir horizontal portions are not provided with bends or corrugationsand of course include hangingor drop wires without bends or corrugationsin their horizontal portions.

Having described my invention, I claim as-
